What are the best and quickest ways to ruin an engine?

I'd say not changing the oil or allowing the oil to run low is a dead cert and quick way to cause issues?

Do cold starts matter that much?
 
Fitting a spanky new induction kit and routing the air feed really low into a fog light or placing it in the lower part of the grill with a shiny anodised inlet. Then pretend you a rallye driver and bomb the through the first ford you can find. :p

Id say cold starts do make a difference but as long as the oil is changed regularly and it is given a gentle warm up the effects can be minimised.
You can aslo ruin an engine by making it out of mashed potatoes .
 
Buy a skyline with standard turbos and a boost controller and set it for 1.3 bar

Job done

Then your mates can post that another gtr has blown up
 
IF you don't want to ruin your motor then DO NOT
1 Let it idle to warn it up.
2 rev it out before it is fully warmed up.
3 use poor quality oil and extend the oil change period.
4 turn the boost up too far on a stock engine.
5 rev it past the redline constantly and eventually you will experience electrical problems when a rod punches thru the block and damages the alternator.
There are many ways to damage an engine and shorten it's life.
 
Sand in the fuel tank is a good one... :Lol:

HDi, what's a cold stop? Running for a second then turning it off?
 
Switching off (especially a petrol engine) after a short journey. Leaves lots of moisture and acidic gases inside the engine which causes corrosion and oil dilution. This causes far far more engine wear than the cold start itself.

It's the reason that a car that does a one mile journey twice every day will be far far more worn than one that does a twenty mile journey twice a day every day.

If the wear was due to engine startup then both are experiencing the same number of cold starts and we would assume that the lower mileage car would exhibit less wear.

Taxis get extremely high mileage due to the fact that the motors are hot most of the time so there are fewer cold starts a little to no condensation etc as HDI has mentioned above.

Thanks for the explaination! :)
